Should i put Effects on the same layer or same family?

Hi,

I'm working on a platformer game for android.

For the enemy, every time they are hit by the player, i want to set the brightness effect to 100 (white).

Should i put the Brightness Effect on the "Enemy Layer" Or "Enemy Family" (Performance-wise) ? (Or is it the same?)

Also, i want to put "GlowHorizontal & Glow Vertical" Effects on certain sprites that are not on the same layer

Ex: I want to put Glow to:

- Player -> Which is on the Player Layer

- Enemies -> Which is on the Enemy Layer

How do i achieve this effects with the best performance?

Thanks
